This chapter contains local and remote system administration information to help you perform the
routine tasks needed to maintain your thin client environment.

Restoring Default Settings
Depending on the default settings you want to restore on the thin client, you can do the following as
• Use the BIOS to restore default values for all the items in the BIOS setup utility For more information,
see Accessing Thin Client BIOS Settings.
• Re-image the thin client to restore all factory default settings using the WDM, For more information,
see Using WDM Software for Remote Administration. The Dell Wyse 7040 Thin Client has bigger disk
size, where any re-imaging will require compression.
– A raw read/write of the disk can be performed because WDM Imaging solutions are sector based.
The time required for any imaging is directly proportional to the size on disk occupied by volumes.
– Volume shrink is supported. In additional to this feature, you can perform either Custom Sysprep
or Config Manager Sysprep. This is to address capturing from larger disks (as in the current
scenario), without spending the proportionate amount of time.
– After you start a custom sysprep or config manager sysprep process, a window is displayed. Use
this window to shrink the OS volume. You can use the Disk Management option to shrink the
– This reduces the time required for capturing the image from WDM during Custom Sysprep.
– However, this step is not mandatory for Config Manager Sysprep as the imaging solution is SCCM
in this scenario and is file based WIM capture/deploy.
